Which command is used to update npm to the latest version? a. npm install npm@latest -g b. npm update npm -g c. npm upgrade npm -g d. npm install npm -g

To update npm to the latest version, the most appropriate command is:

a. npm install npm@latest -g

Explanation:

1. Command Breakdown:

   • npm install: This command is used to install packages.
   • npm@latest: Refers to the latest version of npm available.
   • -g: This flag indicates that npm should be installed globally, making it available system-wide.

2. Other Options:

   • b. npm update npm -g: This command is not commonly used for updating npm itself. It updates packages listed in the package.json file.
   • c. npm upgrade npm -g: This command is incorrect since "upgrade" is not a valid npm command.
   • d. npm install npm -g: This command installs npm but does not specifically update it to the latest version.

Final Answer:

Therefore, the correct answer is a. npm install npm@latest -g.
